pressure spike

14. On-board data logging

.csv file format

15. Quad Flow Sensor
Specifications:
• Bi-directional measurement capability
• ±1% full scale accuracy
• Pressures up to 345 Bar (5,000 PSI)
• Temperatures to 150 °C (300 °F)
• Four flow ranges, two nominal port sizes:
4 - 56 LPM SAE 12
7.5 – 94 LPM SAE 12
11.5 – 227 LPM SAE 16
15 – 321 LPM SAE 16

16. Quad Flow Sensor - Operating Principle
• Two magnetic pick-ups, positioned out of phase
• “Quadrature” displays and counters detect the
leading or lagging phase of the turbine rotation
– Time period between frequency pulses has a different
start/stop time (phase) depending upon forward or
reverse flow
– Consider: clockwise motion from Pick-up #1 to Pick-up
#2, compared with counter clockwise motion

17. Operating Principle (continued)
• First pick-up is used to determine flow rate only
(both directions)
• Second pick-up is used to determine phase:
– Voltages between pick-ups are compared
– When peak voltage on pick-up #1, voltage level of
pick-up #2 will determine if the output signals are
leading or lagging each other
– Phase calculation determines flow direction

18. Quad Flow Sensor Applications
• Bi-directional flow measurement in any hydraulic
system
• Monitor/Governor for hydraulic system:
– Bi-directional flow rate can be used to provide a
“NET” total to the customer:
positive flow - negative flow = NET flow
– NET total can provide data regarding other aspects of
hydraulic system, for example cylinder travel
– Therefore, cylinder travel can be a parameter used to
regulate other areas of the hydraulic system

19. Applications:
• Fork lift speed regulation:
– Fork lift manufacturer uses Quad sensor to determine
height of the forks. This information is used to limit the
maximum operating forward speed of the truck (as forks
go higher, maximum truck speed goes lower).
